The overview assumes that you have installed the ALC control power adapter correctly, and according to the applicable manuals in the following car models:

• Tesla Model Y (all model years)
• Tesla Model 3 (2019 - 2023)
• Tesla Model S (05.2016 / facelift ->)
• Tesla Model X (all model years)

NB! ALC can only be used for controlling 12V relay wiring. ALC must under no circumstances be connected directly to a light source / LED.

In case of problems along the way, spend a maximum of 30-60 minutes on troubleshooting. Contact bilkomponenter.no if you have problems for which you cannot find an immediate solution.

NB! In the event of a fault with the car's headlights on the driver's side, where ALC is connected, contact us immediately.

Temporary deactivation and activation of ALC and auxiliary lights - while driving

• Deactivate - Flash five / 5 times with light horn while driving.
  • This temporarily disables ALC so that the auxiliary light is not activated together with the car's main beam.
• Activate - Flash five / 5 times with light horn during the same drive.
  • Activates ALC again so that the auxiliary light switches on/off with the car's main beam

If ALC is temporarily deactivated while driving - but not activated again - ALC will always be activated if you park the car and lock / switch off the car for a few minutes.

Permanent deactivation and activation of ALC

NB! The points below only apply to ALC with firmware lower than 24.8.1. For ALC with firmware higher than 24.8.1, permanent deactivation and activation can only be done via a laptop over wi-fi, or via app (App has not been launched as of 29/03/2024).

Should you wish to disable ALC and the extra light permanently, this is also possible.
Please note that if you disable ALC permanently, you CANNOT activate ALC while driving as described above.

1. Park the car and put the gear selector in "P"
2. Make sure the car is on, and the lights at the front of the car are on
3. Enter the light menu on the screen
   1. Turn off automatic high beams
4. Turn off all exterior lights
5. Within 4 seconds after the lights on the car are switched off - flash the light horn on the car 6 times
   1. On the sixth flash, you should see that the additional light does not tend to match the car's main beam

To activate ALC permanently again, repeat the procedure as described above. At point 5, the sixth flash of the light horn will cause the additional light to come on again as a confirmation that you have activated ALC.

 

IMPORTANT! ALC and additional lights fitted to cars with a lithium 16V low-voltage battery.

Under given conditions in very cold weather (below -20C temperature on the low-voltage battery, and led activated continuously for over 30 minutes).

Due to the way the low-voltage battery and its BMS work, you may experience error messages in the car in these situations. Any error messages come from the low-voltage battery's BMS not requesting enough current to cover the current draw from the auxiliary light. The error is not serious, and is easily resolved by deactivating the additional light as described above for 10-15 minutes while driving so that the low-voltage battery has time to recharge.
